Sure they do they just lack fabrication facilities.
 


I know, when I say they "make" some quality units I meant sell.
 


I agree. Bought several cheap PSUs. Ultra and Basic. One of them took out my motherboard, cpu and graphics card.

 


You guys make points well made about Corsair. I bought an RM750 gold and the thing fried my computer. It had been recalled under specific serial numbers and I had one. It started random black outs and for one summer I thought it was a software problem. Trying to find out exactly what was damaged was time consuming. Because the cpu, motherboard and gpu didn't show problems all at once, needed stress or a long warm up to expose it was damaged.
A small Corsair water cooler H55 didn't have enough liquid in it, garggle and drew 100+ idle temps. A Corsair Carbide 330 R case had holes that didn't match the Asus P8 Z77 motherboard, was warpped (probbably in shipping). I literally pounded this case back into a usable shape. Corsair's products are a real disappointment for me.
 


I'd better keep my finger crossed then with my new RM650i. However the RM uses cheap secondary capacitors, while the RMi uses all quality Japanese caps. (That's what everyone bangs on about anyway.) You got me wondering about the serial number though. I should look mine up. I thought the issue with the RM series was fans not switching on. That was meant to be a bygone issue with new stock now, and my fan comes on for sure by itself.

Not meaning offence but your post does poke at Corsair, quite rightly so if it damaged you equipment. Whereas I have constant issue with other so-called quality manufacturers. Noctua fans, absolute nightmare. Gigabyte mid-range Graphics cards; I feel like I would never want to buy another again. That's after three in a row with issues.
 


Good on you. Sounds like Corsair made improvements. Gigabyte did have some problems with some video cards. I blame the BitCom craze for the mass of inferior AMD cards. However, old video drivers, overclocking optimizers for Nvidia cards are a problem when replaced with an AMD video card. They, and the games have to be rooted out from C: drive, paths to the registry, directories and user's files.
Yeah, that computer went by-by two years ago. I salvaged the ram, WD hard drive and an LG disc drive. What 's working from a spare computer is a Corsair H-100 watercooler and a few 120mm fans. They're efficient and keeping the cpu temps down, but even they had fan mount problems (screws were too short).
You know, I have friends who'll swear Corsair love all day and all night, t'was the best thing in their life. Like you, I just happen to be the guy who ate three zeros. Yes!, the recall was a fan switching problem. Sometime after 6 months ownership, on the cusp of summer, it was going south. The computer would crash from once a week, every three days, two days, every 6 hours to 2, etc. There was high heat only in traces (probably because the fans weren't on to blow the heat out) and I didn't have temp reading for the psu. Sometimes when it crash, the psu fan didn't stop. ?That's what made it tricky and kept me thinking it's a software problem.
I RMA 'd the RM750 and gave to a friend, got an XFX XTR 750 to replace it. At the time, I don't think it's the best I could've bought. It was a SeaSonic made thing so I suspected some quality and it's been good. I just couldn't find a Seasonic X model in stock.



 
Hello everybody,
Thank you first for the many "Psu tier list 2.0" which brought me invaluable in reducing my research.

I need advice on the part (noise) power supply to finalize my choice. (I have for the game)
i7 4790K I want Oc
R9 290 x 2 I want Oc
Fan 7 + 2 SSD + Cpu air cooling

A 1000w power supply is not sufficient?:
(From the cheapest to the most expensive 170 à 189 Euro)
- XFX XTR 1050w
- Corsair RMX 1000w
- Corsair RMI 1000w
- Cooler Master V 1000w
*Supernova G2 1300G ( If in discount )
I have already ordered a lepa g 1600 (because 149 Euro "in discount") but makes noise (Fan) barely connected 0% => 10% / 20%/3.. load.
Could you give me the quietest redesigning the list please.
(Or maybe another model in the same price range)

Thank you to you well in advance. "' sorry for the Google translation '"
 
Hello Black / Dotto and thank you sincerely yours.

Excuse me ( but between google translation and the very bad surprise noise emitted by the fan Lepa G1600 ~..~" ) I prefer to make it clear to be sure.

I request information about power supply with the quietest fan of the list ( for crossfire R9 290 / at around 180 Euro ), which is reduced to either the Cooler Master V1000 to either the Supernova G2 1300 ?

Sorry again for the Google translation

I myself am very happy with the RMi series from corsair. the fan virtually never has to spin. gold rated and 7 years waranty. and from what I ahve been reading, excelent built quality
 
Tiny, Tsu, Black, Dott
Thank you sincerely yours.

I miss him to wait promotion on the supernova G2 1300 if not I would take one of the two Cooler Master V1000 or Corsair RMi1000.

Again thank you, to your site and this forum thread. ( huge helping hand )

Gotta deal with a rebate, but if you can buy from Newegg this is a really good unit; essentially a Seasonic S12II 620 watt psu with a slightly different internal layout (nothing to be at all concerned about). $20 rebate makes this a really good deal.

Sorry, didn't see the date of your post. This Antec is on sale through today 11/26.
Here's the Seasonic and no hassling with a rebate. BUT it is NOT at all modular.

The +5V rail going out of spec proves otherwise. It's a Seasonic M12II-620 with minor differences, mostly on the modular PCB, so it uses the same outdated double forward group regulation design.
