EVGA 450W B1 vs. 450W B3

[destinywarlock55]

Hello,
I'm trying to choose a power supply for my build, but i cant settle on a EVGA 450W B1 or B3. (I already know that the B3 is fully modular).
P.s I'm not going to be upgrading my PC so that's why I'm going for a low wattage PSU.

My question is what's the difference between B1 vs. B3? And is there really a big difference?
Thank you!

Both aren't very good AVOID them.

what PSU do you recommend them? And why are they not good?

If you need a good quality unit for a good price then I would look at the CX 450M.

And why are they not good?

B1 by HEC has some soldering quality issues. Double forward, group regulated is something you'd see in a PSU almost a decade ago.

B3 saw a bit of bait and switch. Actual retail sampels had poor build quality and lacked certain protections.

If you need a good quality unit for a good price then I would look at the CXM 45W.

Pretty sure you meant CX450M.

CX450 would be even better. Even though it's non-modular, it uses an LLC topology instead of double forward, but both have DC to DC.
