hec HP585DB 585 W ATX12V Power Supply - Power Cord Included
hec HP585DB 585 W ATX12V Power Supply - Power Cord Included

Pros: Not the best power supply, but contains features such as Over Current Protection (actually kicks in at about 350W), Over voltage Protection, Under voltage protection, a step above most cheap power supplies in this price range. Basically, if you need a cheap power supply to power a lower-watt computer and you don't want it to blow up, this guy will do the job. Cabling is better than most cheap power supplies.

Cons: Some parts like input filtering and other things on the inside that are missing, makes it cheaper, but these things are important to the correct operation of the power supply.

Overall Review: You can buy A LOT worse at this price range than this guy. This is based on the same unit as the thermaltake TR2-430, which in real load testing reviews shuts itself off at about 350W.

Don't do it, please don't

Broadway Com Corp P4-OKIA-550-RB 550 W ATX 12V v2.2 SLI Ready CrossFire Ready Active PFC Power Supply
Broadway Com Corp P4-OKIA-550-RB 550 W ATX 12V v2.2 SLI Ready CrossFire Ready Active PFC Power Supply

Pros: Umm, fans and casing are of higher quality than most cheap psu's

Cons: If you open it up, you will find it to boast (up to) a CWT 235W, at least that is the highest watt that the PCB is silkscreened for using a 5A, 250V fuse, which is what this uses. There are so little 12v holes on the PCB they had to funnel all three of the (20 gauge, should be 18 gauge,) wires for the pci-e connector into one 20 gauge wire. Same with the 8 pin cpu connector. There is really only a single 12v rail. The 12v was rectified by a 20V (just means the maximum it can rectify,) 16A schottky. Minusing the combined 232.5W capacity for the 5v and 3.3v, you get 317.5W. Divide by 12 to get the amperage of about 26A. Now, since when did 26=16? The 5v was rectified by a 40V, 20A part, and the 3.3v was rectified by a 20V, 16A part. Dosen't sound like the label at all, does it? The capacitors used are Asia-X, a brand related to fujiyuu, not known for quality capacitors.

Overall Review: Don't cheap out and buy this, seriously a power supply is easily one of the most important as well as overlooked part of the computer. No continuous rating for that 550W max output, perhaps it means it will do it for just a millisecond before exploding?

Meh

Diablotek PHD Series PHD350 350W ATX12V V2.2 Power Supply
Diablotek PHD Series PHD350 350W ATX12V V2.2 Power Supply

Pros: Nice finish on the exterior, nicely sleeved cables. Overall a very attractive unit sans the huge label diablotek puts on it, but even most of that is black so its not a huge deal. Fan runs full blast, but is fairly quiet.

Cons: Cables are real short. Sata and molex connectors are alright, but the motherboard, cpu and pci-e connectors are way too short. Overall build quality is lacking with undersized transformers, low value schottky diodes and low value primary switching transistors. Low value cheap chinese filtering capacitors on the output.

Overall Review: Fine if you keep the load under 200W, but I wouldn't trust it for anymore than that.

Ehh

APEVIA JAVA ATX-JV650W 650 W ATX12V / EPS12V SLI Ready CrossFire Ready Power Supply
APEVIA JAVA ATX-JV650W 650 W ATX12V / EPS12V SLI Ready CrossFire Ready Power Supply

Pros: Somewhat attractive exterior with blue led, sleeved cables.

Cons: Not 80+ certified. Sunbeamtech may rate it at 80%, but it's not 80+ certified. It's not listed on the 80plus's website, and in order to be tested by the 80plus organization it must be APFC, which this is not as evidenced by the voltage selector switch. But, again, it is not 80% efficient. No Non-APFC can do more than about 75%, especially at this cost. Don't expect it to last too long.

Cheaply made junk

LOGISYS Computer PS575XBK 575W ATX12V SLI Ready   Power Supply
LOGISYS Computer PS575XBK 575W ATX12V SLI Ready Power Supply

Pros: Quiet

Cons: Soldering is terrible, large blobs of solder that could short out against the case, with no insulation between the case and the pcb. Low quality chinese capacitors, the primary switchers are not even good enough for 350W of output, and the secondary schottky diodes are as follows: 12v-20A, 5v-30A, 3.3v-20A. Those ratings are no where near the ratings on the label. The heatsinks are not big enough to carry away the heat generated by these either. This is a unit based on a very old design with a new label on it, and it uses parts from back in the AT era of power supplies. Inefficient, and wayyyyy overrated. Fans are NOT temperature controlled, they are soldered directly into the 12v holes on the pcb, and they are quiet and do not push very much air. Concerning if it got hot, especially with those cheap capacitors. 2 transistor 5vsb circuit is cheap and low quality, can cause the 5vsb to go out of spec and fry your motherboard.

Overall Review: I venture to guess it will blow up before 350W. And to all those people saying they are running some super computer on this, you are lying. No one who will spend $600 on a computer is going to spend $25 on the power supply. A core 2 duo with a 9800gt will not "load" this power supply to 575W. Maybe 250W under 3dmark or furmark, which are both not anywhere close to real world scenarios. Once you pop in that gtx280, well, you will hear just that, a loud pop.

Good so far

Rosewill 350W ATX 12V v2.2 Power Supply - RV350-2
Rosewill 350W ATX 12V v2.2 Power Supply - RV350-2

Pros: Quiet sleeve bearing fan that is temperature controlled, and is a globe fan. The main transformer and secondary side schottky diodes are high enough capacity to meet the labeled specs, finally a cheap power supply with an actual bridge rectifier, lots of input filtering, nice connectors and thick enough wire for what power output this is

Cons: Capacitors are of a more...poor quality, but do their job. Primary switchers are of questionable capacity. I would put this down as a good 300W psu, 350W may be pushing it. Manufactured by Solytech enterprises, also known as the infamous Deer computer company.

Overall Review: What do you expect for $25?
