5 out of 5 eggsIf it's Late Nite, it must be Larry!

Pros: - Price
- 80 PLUS Certified
- 650W
- Very well packaged w/plenty of spare H/W
- Killer Rails
- Fan stays powered on after CPU shut-down, until the internal PSU temps are at nominal values
- Blue LED fan
- It's "a poor man's rich power supply"

Cons: - No modular cabling....but I knew this when I entered into the relationship ;- )

Other Thoughts: This is by far!!! of the very best PSU's that I have ever utilized in a custom build, with regards to price-to-efficiency ratio, as compared to other name brand PSU's in the same Bronze or 80 PLUS certified category. It's virtually unheard of to find a PSU with these type of specs, in this "type" of price range.

3 out of 5 eggsOK power supply

Pros: Has 2 6pins which will run my vid card. More wattage for my system had a 460w power supply had to upgrade do to a new vid card.

Cons: First power supply i got was crushed during shipping so newegg sent me another one. The only problem is when i power down the computer then turn it on again the hard drive is not powered, but when i turn the switch off (after the offline cooling cycles threw) then back on then it works. It is more of annoyance than it is a problem. Have to do this every time I power down the computer.

1 out of 5 eggsNo support

Pros: Worked fine for a year.

Cons: No response from Tuniq US customer support (they only work 15 hours/wk).

Other Thoughts: Computer ran fine for just over a year, then started randomly rebooting. The computer may run for 2 hours but usually reboots after a minute. Replaced the memory, video card, and had the mobo checked by the manufacturer. The problem remains. Suspect a bad power supply. Contacted Tuniq PSU warranty support in the US (SunBeamTech US) for an RMA, but have not received any response.

5 out of 5 eggsGood Power Supply

Pros: Quiet

Cons: No Problems whatsoever.

Other Thoughts: It works, that's all I need from a power supply.

It's been powering:
AMD Phenom II x4
EVGA Geforce 9600 GT
Samsung 500GB 7200rpm HDD
Gigabyte GA-MA790-UD4P Mobo
for a year and a half now (about 10+ hours a day), and I have had no problems with it at all.

The logo is also pretty cool looking IMO.

4 out of 5 eggsNot too shabby

Pros: Overall build quality of this power supply is decent. It was solid and the wires were long enough.

Cons: After unpacking I've noticed that something was rattling on the inside, after looking through the ventilated side I've noticed that a piece of plastic film typically used for isolating parts from each other was dangling around. I had to remove it so that it didn't hit the fan.

Other Thoughts: So far it's working fine, it's very quite and now I barely notice my computer being turned on.
