5 out of 5 eggsalmost 1 year of continous uptime... still going strong.

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: Price because for that and having a stable 24/7 power supply is very cost effective.
very very much tested on real live voltage spikes and brownouts and ignored it.
Above average airflow for a P/S, due to the better hexagon hole shaped grid, but could be better...

Cons: none other then,
still has the very poor design like 99% of power supplies that have with a 90 deg angle change of airflow. Straight-thru always works better.
Has one single set of power leads daisychained for 6-8pin GPU plug with the same gauge wire. Instead of one thicker main wire and then a smaller jump wire for the daisychain, or two matching pair sets of leads (even better...)

5 out of 5 eggsCooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: Good Brand
Price
Quiet

Cons: None.

Other Thoughts: I had to get an extender for the 4 + 4-pin +12V CPU connector, I have a Tesseract (Red and black with a side window) case, so the Cooler Master is bottom mounted. The cable could reach if not utilizing the cable management capabilities of the case, but did not take an Egg off review for this, as it is for completely cosmetic reason that I did this.

4 out of 5 eggsDecent and cheap

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: - Price
- Could power FX 8320 & R9 270X

Cons: - Not even bronze certified
- Occasionally fails with GTX 970

Other Thoughts: Had no problems with an FX-8320 and R9 270x. I upgraded to a GIGABYTE GTX 970 4GB G1 GAMING SOC and the PSU works for the most part. It does fail occasionally, however. I've also heard that this isn't really a 550w PSU.

3 out of 5 eggsNot 550w

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: it was cheap,and a decent brand

Cons: it's not 550w as stated. it's actually 384w

Other Thoughts: should have checked it out a little further. had thought 550w meant this thing pumped out 550w. so i purched a EVGA 960 GTX vid card that keeps shutting the whole pc down. the card states needs 400w .. and i thought i had 550w ... booooo

3 out of 5 eggsGood for the price.

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: -Cheap

-Quiet for the price range.

-Works great for the price.

Cons: -It's not 80+ certified.

-While not having sleeved cables is not a con, having the cables be all one color would have been better.

-Not actually a 550W unit.

-Has a sleeve bearing fan

-The 24 pin cable is a little short even for my NZXT 210. But not worth taking a egg off over .

Other Thoughts: I bought this as a stop gap until I could afford a better PSU. It's cheap, which is a plus and is quiet for the price range. I've put about 50 hrs on it( and will probably put on another 10 before my new PSU arrives) and have had no problems.

This review is from: Cooler Master Elite V2 - 550W Long-Lasting Power Supply with Full Electrical Protection (OVP / UVP / OPP / OCP / SCP)

Pros: Cheap for 550w

Cons: CPU power isn't long enough to stretch across my mid tower case with ATX MB. I couldn't route the cable through the back of my case
