RTX 5090 TGP 575W (NVIDIA spec) + Ryzen 9 9950X3D TDP 170W + motherboard X670E + RAM 64GB DDR5 + 2x SSD NVMe + 4x case fans ARGB + RGB strips = ~870-900W sustained 100% load. Plus 25-30% margine pentru spike protection RTX 5090 transient peak (Blackwell peak 2x sustained pentru 100µs), plus capacitor aging future-proof 5+ ani sustained operation = recomandat 1200W minimum, 1500-1600W safer. PSU specific 1200W ATX 3.0: Deepcool GamerStorm PN1200M (4 199 MDL value), Corsair RM1200x (5 500-6 500 MDL premium), be quiet! Dark Power 14 1200W (7 499 MDL silent premium). 1500-1600W enthusiast: be quiet! Dark Power Pro 13 1600W 80+ Titanium (10 649 MDL flagship). Pentru build cu RTX 4090 + Ryzen 9 9950X3D (mai vechi gen): 1000W sufficient (Dark Power 13 1000W 6 699 MDL). Pentru build entry RTX 4060 + Ryzen 5: 550-650W 80+ Bronze (PK500D/PK650D Deepcool 800-1100 MDL).

Efficiency rating @50% load: Bronze 82-85%, Gold 87-90%, Platinum 92-94%, Titanium 94-96%. Calcul economic pe 5 ani build gaming 6 ore/zi @500W sustained load: total 5475 kWh consumat la wall. La 3.5 MDL/kWh Moldova: cost electricitate 5 ani = 19 162 MDL (Bronze 82%), 18 252 MDL (Gold 87%), 17 482 MDL (Platinum 92%), 17 040 MDL (Titanium 94%). Saving Titanium vs Bronze pe 5 ani = 2 122 MDL (acceptable dar NU justified premium PSU 3 000-5 000 MDL). Saving Platinum vs Gold = 770 MDL pe 5 ani (NU justified +1 500-2 500 MDL premium Platinum). Pentru build mainstream cu utilizare 4-6 ore/zi: Gold sweet-spot universal (saving Bronze nemarginal). Pentru build sustained 24/7 server/workstation: Platinum/Titanium clear (saving 1 500-3 000 MDL pe 5 ani justified). Pentru build occasional sub 3 ore/zi: Bronze acceptable (saving Gold negligible).

ATX 3.0 (2022+): connector 12VHPWR 16-pin pentru RTX 4090/5090 cu sustained 600W single cable, plus spike protection 200% pentru 100µs transient. Toate PSU-uri be quiet! Dark Power Pro 13, Dark Power 14, Pure Power 13 M sunt ATX 3.0 nativ. Deepcool GamerStorm PN/PQ/PX series toate ATX 3.0 nativ. ATX 3.1 (2024+): connector 12V-2x6 revised cu safer pin layout (rezolva 12VHPWR melting issues 2023 RTX 4090 reports), same 600W max. Pentru build new 2025 cu RTX 5090: ATX 3.0/3.1 mandatory (zero adapter need). ATX 2.x legacy (pre-2022): PSU vechi cu connector PCI-E 8-pin tradicional, necesita adapter 3x/4x 8-pin la 16-pin 12VHPWR (incluse cu RTX 4090/5090 box dar overhead 6+ inch cable management plus risc adapter fail thermal). Pentru build cu RTX 5090: PSU ATX 3.0/3.1 nativ clear winner. Pentru build cu RTX 30-series sau AMD RX 7000 (zero 12VHPWR): ATX 2.x acceptable cu zero adapter needed.

Modular full (Deepcool PN1200M, Corsair RM1200x, be quiet! Dark Power Pro 13): toate cabluri detachable inclusiv 24-pin motherboard + 8-pin CPU + PCI-E GPU + SATA + Molex. Avantaj: cable management premium showcase build cu zero cabluri unused stuffed in PSU shroud, aesthetic clean pentru case cu tempered glass side.

Pure Power 12): cabluri esentiale soldate fixe (24-pin motherboard plus 8-pin CPU) + restul detachable (GPU/SATA/Molex). Sweet-spot value pentru build standard non-showcase. Non-modular (be quiet! System Power, Deepcool PK500D entry budget): toate cabluri soldate fixe permanent. Cost minim dar cable management challenging (cabluri unused trebuie ascunse forcata in PSU shroud sau zone neutilizate case). Pentru build showcase ARGB cu tempered glass: modular full clear. Pentru build entry hidden case fara showcase: non-modular value pure (saving 300-500 MDL).
