I've got a noobish question to ask a product warning to share.

If I am using a 750w PSU for an S1 that is only using 360w am I still paying the the remaining power? As in, am I still paying for 750w even if I am currently only 360w to mine?

No, the PSU has a 750W capacity, but will only use 360W + a bit for inefficiencies.

OK, thank you for the information.

Beware of the Sentey brand of PSUs. The prices are indeed too good to be true. This one in particular keep losing power and within a day caught on fire. I will always read the low ratings first before buying something from now on.

Glad I can't see the Seasonic 1200W Platinum on there.

I have 2 and they are expensive, but the cables are cheapo.

Firstly, they are 18 gauge ribbon cables, which I was surprised to find, after having good 16 gauge cables on my 2 older ~$100 cheaper OCZ 1250Ws
Secondly, the plastic cable to PSU connectors on the cables/PSU are difficult to plug together properly.

I couldn't get any of the Seasonic 1000s when I needed the 2, so I got the 1200s Sad

No idea if the 1000s have these same issues.

I would say 18AWG is pretty standard over most PSUs, but yes @ 1200W that's a bit unusual.

Scanned the thread for suggestions and couldn't find the corsair cs series mentioned.

80PLUS Gold

Semi modular
450-850W

Added CS, just waiting on Theymos to inject me some additional posts as I'm at the character cap.

What r your thoughts on the 750 and cs850

Doesn't seem to be a justification for the price premium over the CXMs. Yes its a higher efficiency but that's about it.

Personally, I'm shocked at your rating of the EVGA 1000W PSU. I also noticed that you didn't differentiate between the G2 and the P2.

I run a 1000W P2 myself. It actually has a 0db noise level at most loads, thanks to the eco switch on the back of it that only runs the fan when it's needed. Sure, the cost is higher than some others, but it's a lower rating than I'd expect. Also, the price of the 1300W has gone down a lot recently, and EVGA just released a 1200W P2.

The 10-year warranty doesn't seem to factor in to your calculations either.

Yes it does. The larger units simply don't compete in the rating due to their $/W.

I'm not saying it needs to have the highest rating, but I'm just saying it's a off.
For example, you rate the Corsair RM 1000W a 77.7. This unit has nearly identical specs to the 1000W EVGA, except it's less efficient, and has half the warranty. In light of this, I think the EVGA 1000W needs to be at least a 78. I imagine that this rating was done when the EVGA 100W was closer to the $300 range and never recalculated.

You should also differentiate between EVGA's gold and platinum series in your ratings.

No it actually has a lower rating because its 1000W is a strict 1000W rating. Corsair's 1000W rating is 1000W 24/7, and is really 1100W by the same modicum. Both were snapshotted at the same ~$200 price.

The EVGA SuperNOVA 1000 G2 has arrived! This power supply is 80 Plus Gold Rated, offers 1000W of continuous power, exceptional efficiency and is fully modular.

Hi, great guide. Takes care of digging up how many pcie connectors a psu has.
Could you add Corsair HX1000w I just bought one on ebay and don't know anything about it.
Thanks
