Best Match for an RTX 4060 Ti1 of 5
MONTECH Century II 550W
Montech's Century II 550W is a fully modular 80 Plus Gold unit with a native 12V-2x6 cable and a 10-year warranty, unusual at this wattage.
Best for
- Builds that will keep this card.
Skip if
- Skip it if rated output matters most to you; the SAMA GT750 offers 750W.
Why we like it
Its 135mm FDB fan has a zero RPM mode, and it uses 100% Japanese capacitors. The silver metallic finish is MONTECH's signature look. It is ATX 3.1 and PCIe 5.1 ready with a 12V-2x6 cable.
On rated output it trails the group at 550W, while the SAMA GT750 offers 750W. It also offers a 135mm fan that can stop at low load. The MONTECH Century II 550W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
No depth is rated for the MONTECH Century II 550W, so check the maker's page against your case's PSU bay. Its price falls between the SAMA GT750 and the be quiet! Pure Power 12 750W, based on our last check.

Best Budget 750W2 of 5
SAMA GT750
SAMA's GT750 uses Japanese capacitors with an LLC and DC-DC design, a native 12V-2x6 cable and an ECO silent mode for low loads.
Best for
- Leaving room for a bigger card.
Skip if
- Price-first buyers should look at the darkFlash DG750, which cost less when we checked.
Why we like it

Why we like it
Its warranty is 5 years. It is fully modular with a quiet HDB fan, 80 Plus Gold rated, and backed by a 5-year limited warranty. Its fully modular cables reduce clutter for first-time builders.
It matches the SAMA GT750 and the be quiet! Pure Power 12 750W on rated output (750W). It also comes with a 140mm body that leaves room for cables. The darkFlash DG750 comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
