HIPER HPU-4K580-MS 580W ATX12V v2.2 SLI Certified CrossFire Ready Modular Power Supply

Pros: Modular connectors are nice to have. It worked for a bit more than a year.

Cons: I bought two of these for two new computers in the summer of 2006. A month ago the first one failed. Then last week the second one failed. Looking on the internet I now see this is common with these units. I've since emailed and called the US branch but they're not responding.

Pros: Looks great, modular cables seamed strong and had a nice connector.

Cons: After 1 year and 1 week it died. I was running it 24/7 with no problems whatsoever. Turned if off one night, tried to turn it on the next day and nothing.

Overall Review: Read the other reviews here. I'm not the first person to have this PSU fail after only a year. And I'm still waiting on getting info to start the RMA process with them. I'm going to purchase something different while I wait.

Pros: comes with handy cable wraps which help minimize the clutter of wire, etc. inside the PC case

Cons: despite having a couple fans onboard, this PS seemed to get cooked on a particularly hot day in my SoCal second-story apt (no A/C). Newegg was nice enough to promptly replace it

Pros: Good PSU would recommend to anyone

Cons: Doesn't come with an 8pin connector 0_o

Overall Review: you should check if your Mobo needs an 8pin connector this PSU only comes with a 4pin but you can get the 8pin separately model HLC-2M1P-15 thats what i did

Pros: okay so I JUST got this thing in the mail after waiting the prescribed number of days (UPS = slowish, but cheapish) and wow. the package/toolbox is awesome, and will make a great toolbox for when I go to LAN parties and stuff. the PSU itself is a monster! its about 1.5 times the size of the dinky 430W that came with my case. the cables are nice and tidy looking, plenty of length for whatever case you've got (i have to tuck the mobo power cable into an open 5.25" bay! VERY quiet if not silent.. I can't hear it over the stock HSF on my Athlon 64 (soon to be ditched for something a little less noisy.

Cons: not really a con on the PSU, but rather my case I think.. one of the mounting holes didn't align with the one on the case, but its not a big deal, as I will be trading up for a better case soon anyway.

Overall Review: overall i'm impressed with the unit and the presentation! I love being able to use the SATA power connecter and an actual PCI-E connector, although I would have liked to have seen a second dedicated PCI-E cable, but I'm only running one card right now anyway. and if Hiper comes out with a new version with 2 dedicated PCI-E lines, I'll definitely consider it. DISCLAIMER: I have only had this thing for about half an hour, so these are just first impressions!!!

Pros: Great power. I've got a fairly power hungry system (4GB ram, OCed processor, 8800 GTS, 2xHDs raided) and it keeps it strong. No problems. Its my first modular power supply, and I'll never buy a regular one again. Cables are sleeved perfectly for any combination of cables you want. Fans provide good airflow.

Cons: Doesn't have actually SATA power cables, just adapters. Don't get me wrong, they blend in and work fine. Just wish they would've included the raw plug. But they work fine, so its purely aesthetic.

Overall Review: It only has a 12v 4 pin CPU connector, not the 8 pin EPS12V. But it doesn't need one, as it provides enough power on the 12v rail(s). I have a 3.0ghz Core 2 Duo processor overclocked @ 3.36ghz with slightly upped voltage and it runs it rock solid no problem.

Pros: Awesome look, very quiet operation. Cable connection points to power supplier are wonderfull - push pin, with screw on sleeve. Cables are sleeved and thin, reduces clutter in box. Quality construction.

Cons: Not really a con, but a consideration. The connectors at the power supply for the cables are long and rigid, adding 1 to 1.5 inched to the length of the power supply. This is normally not a problem. But if your case is a tight fit for the power supply, this should be considered.

Overall Review: "Tool box" case is great for storing misc. parts after install.

Pros: As has been stated in previous reviews, this thing is beautiful. It is a shame to cover it up. It's not too flashy, and just looks fantastic. The finish is very nice, and the chrome fans really set it off. The modular connectors are the best I have seen. They not only look very good, they also perform well. Very positive retention and a solid connection to the PSU. The cables are also done well. The sleeving is top-notch and the wiring and connectors appear to be of good quality. Cable lengths are varied appropriately, and plenty of adapters and splitters are provided for the average high-end system. Power is stable, and voltages are spot-on across the board. I had to raise the variance in ASUS probe to 10% on the VCore with my old PSU to avoid constant alarms. Now I can set it to 5% where it should be. It is whisper-quiet, and even with the open design, my case temps dropped a couple of degrees with this PSU so I know it is cooling well. It comes in a toolbox!

Cons: Hmmm... A previous reviewer dinged this PSU for the cable selection. I would have liked to have seen at least one dedicated SATA power cable. However, considering the quality of the unit as a whole and the price, I don't consider this a negative. There are ample adapters, and unless you are running a RAID array with 4 drives, you should be fine.

Overall Review: My initial impressions of this PSU are very good. It is very stable, has plenty of power. It is quiet, and has the best modular system I have seen. After having a little time to play around with it, I am wondering how HIPER can sell these so cheap. Let's hope the longevity is as good as the rest of the package.
