This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Havent even been able to register for rebate?
I have been trying for over 2 weeks now?
I called and it says the number is wrong???
The site it sends me to ,asks for the information and i have entered it over 5 times and made sure it was right but i think they dont want to give out rebates,?
I have read similar complaints and bad cusomer service period.
I hear Raidmax is horrible when it comes to giving rebates ,they should simply just give the rebate via debit after you purchase?Maybe it wouild attract more sales?
If i do not get Rebate I will not buy anything from them again?No matter the price.
I could have got a better unit for same price.
It better work and work ,i will make sure they fix it if it breaks or damages anything /including my mobo,or processor? I really hope customer support is better fthan this?

Cons: No customer support and no easy way of getting my Rebate.
I would never go through this again, I would at least appreciate an email and my rebate, its the last day to mail out and i cant even get it registered?
I hope the other site is not selling my information.

Other Thoughts: I hope it works, I wanted to buy More of Raidmax products but if this is the deal im all out,Sorry did not mean to offend anyone involved?
I am building pc's for a living now and they would have had a great customer.
Hope they want to get this resolved

5 out of 5 eggsWorks great

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: No problems whats so ever nice sleeved cabling plenty of connectors, Checked the PSU Rails with a digital psu tester and mine were solid.
Very silent running had a "OK" weight to it.

Cons: none

Other Thoughts: Had a 20$ rebate ,
Raid max isn't known for their great pay outs for Rebates.
We will see...

3 out of 5 eggsGood one

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Nice finish, both psu and cable

Cons: somehow i was not able to get the main 24 pinconnector's clip bith with my mothermobard....this makes me feel uncomfortable, yeah, they connect very tight, leaves no gap at all, but the clip still can't get to its right position, so i have to use some tape to strengthen them...I don't know if this is this psu's fault or my msi b85-g41's fault..and now i still concern about some day it gonna disconnect by itself..

5 out of 5 eggsRAIDMAX Cobra RX-400AF-B

This review is from: RAIDMAX Cobra RX-400AF-B 400W ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply

Pros: Price. Got this Black Friday for $23 and change. Also came with a $10 rebate. This is my 3rd Raidmax Power Supply and never have had a problem with any one of them. The oldest being 5 years. Nice looking PS with Green non LED fan.

Cons: Not Modular but at this price point who cares.

Other Thoughts: Raidmax makes some real nice PS at a reasonable price. I don't see paying a lot more for a PS when Raidmax does just as good of job at a great price.
